Abstract: There is provided a cup (1) adapted to hold a drink, the cup having, at its opening, a compartment (4) holding an auxiliary drink, made up, for example, of milk, which, due to the special shape of the wall (5) which delimits the compartment, is intended to flow in a very gradual manner into the central compartment of the cup, which holds the main drink (8), made up, for example, of coffee. In this manner, very gradually the user mixes the milk with coffee, as desired by many users and not in a single solution as it currently occurs pouring a given amount of milk directly into the coffee.
